Select the correct answer.
A circle with center O. 3 points A, B, and C are on the circumference. A line each slopes downward to the left and downward to the right from O to A and C. Line rises from O to B. Line runs from A to B and from B to C. Angle at B is 70 degrees.
In the diagram, point O is the center of the circle. If the measure of angle ABC = 70°, what is the measure of angle AOC?
A. 100°
B. 110°
C. 140°
D. 130°
